摘　　要：串口是Windows CE嵌入式操作系统应用的常用接口,串口驱动程序是连接操作系统和串口硬件的桥梁。采用流接口驱动与分层驱动相结合的方法对串口的驱动程序进行了设计,重点对设计串口驱动的关键点进行了分析,包括串口寄存器的配置、中断处理和MDD层和PDD层功能函数的实现。旨在对Windows CE下嵌入式设备驱动设计提供设计思路。Serial port is a common interface in Windows CE embedded operating system,Driver program of serial port is the bridge to link operating system and hardware.It adopts the scheme of,driver program of serial port,which combines the layered driver with stream driver.More description of key technologies on driver program is given,including register configuration,interrupt processing,implementation of function in MDD and PDD layer.The intention of this paper is to offer design method to driver program of embedded equipment in Windows CE.
